Just look, for instance, at FPGAs: almost all the tooling is proprietary, very expensive, and very buggy too. Or look at PCB design: Altium seems to be the standard here still, despite Kicad having made huge advances and by most accounts being as good or even better. It took decades (Kicad started in 1992) for the FOSS alternatives here to really catch on much, and only really because PCBs became cheap enough for hobbyists to design and construct their own (mainly because of Chinese PCB companies), and because CERN contributed some resources.
I'm not sure what the deal is with engineers hating collaboratively-developed and freely-available software, but it's a real thing in my experience. It's like someone told them that FOSS is "socialism" and they just reflexively dismiss or hate it.
To get a EDA tool to a useable condition, and debugged to the point where it is reliable enough to actually use, is just a ton of work. As someone who wants to design circuits, why should I do that work? How will it help me design more circuits? I understand why beginners and casual users don't like them because the EDA tools do have a huge learning curve, but once you're there, they are very productive.
For professional engineers the software license is not really a significant barrier. Compared to the cost of labor, materials and equipment it's basically a noop.
